Abstract
Continuous length wire is segmented into predetermined lengths having desired die-coined configurations at severed longitudinal ends in a wire-working machine of the invention. In a single step operation, such wire is simultaneously die-coined and severed to form a longitudinally contiguous pair of wire ends in order to produce such predetermined lengths with desired tapered convex shapes at each longitudinal end ready for use as shaped and severed so as to eliminate subsequent metal-forming steps and certain problems associated with severing practices of the prior art. In a specific embodiment of the fabrication process, coiled wire is straightened and then simultaneously die-coined and severed to form rigid rods with tapered end configurations which facilitate use as a connecting rod during assembly operations, e.g. in the assembly of a metal wire belt. The application also discloses specific embodiments of dies for such process, methods of producing such dies, and die-drive apparatus for moving such dies together for such single step operation and then apart for a subsequent operation.
